Common AEC use cases After basic tuning, evaluate images captured with the tuned device to determine if any of the common scenarios referenced below apply. Increase image brightness in gray chart and resolution chart scenes Reduce saturation of faces with
Dynamic skip frames concept AWB utilizes information from each frame to estimate the illuminant and make an accurate decision. To adapt to scene changes and fast convergence, it may be good practice to run AWB on each frame; however, camera
Dynamic skip frames parameters To view the dynamic skip frames parameters, open a project, click the AWB tab, and click Dynamic Skip Frames in the List View tab. Table 1. Dynamic skip frames tuning parameters Parameter name Description Tuning Factory
Enable 3A debug log messages (3A v5.x and v6.0) Use adb commands to enable 3A debug logs for the specified chipset. MSM8952/MSM8976/MSM8956/MSM8953/MSM8940/MSM8937/MSM8917/MSM8996/MSM8998/SDM660/SDM630 adb root adb remount adb shell setprop persist.camera.mobicat 2 adb shell setprop persist.camera.stats.debug <3A EXIF Debug Mask> Component
Enable AF core logging About this task Some situations require logging without enabling the full-sweep algorithm as described in the previous section. This section describes how to enable AF core logging without enabling the full-sweep algorithm. Procedure Use the following
Enable EXIF debug information (3A v5.x and v6.0) Use adb commands to enable EXIF debug information in captured JPEG images for the specified chipset. MSM8952/MSM8976/MSM8956/MSM8953/MSM8940/MSM8937/MSM8917/MSM8996/MSM8998/SDM660/SDM630 adb root adb remount adb shell setprop persist.camera.mobicat 2 adb shell setprop persist.camera.stats.debugexif <3A EXIF
Enable full-sweep search and AF core logging About this task A full-sweep search is useful for measurement and verification during the tuning and debugging process. It sweeps through the entire lens position range and selects the lens position with the
Enable TOF AF About this task In the AF tuning header file, set enable and aglo_enable as follows to enable TOF AF. Parent Topic: Tune time-of-flight (TOF) AF
Contrast AF (CAF) Contrast AF (CAF) monitors the motion values from the gyro sensor and the sum of absolute differences (SAD) in luma values to detect scene changes and trigger a search. If the change meets the criteria for stability
These examples illustrate how gain adjusts are tuned so that the final AWB output matches a reference phone as much as possible.
